I just bought a boat with a 1985 johnson 90hp oil injected v4 vro and I mixed oil & gas together and put it in the tank. Now engine will not start. I pulled the spark plugs and they were oil & gas soaked. I am going to empty the gas tank for starters but I am stuck on what to do next. Please help so I can get out on the lake and catch some fish.

Too much oil. If that's an oil injected motor you doubled up on it.

Is the oiler in place and operating? I have a 1990 johnson 40 hp VRO. A previous owner had removed the oil injection system. The oil line is plugged and I mix oil with the fuel at 50:1. It's been running for years like that.

"fresh gas /change plugs ,and start using up the mixed gas slowely when you fill up each time.if you think your vro is not working they twell you to mix 25:1 and mark your oil tank to verify oil usage. so it will still run on 75:1 i had to do it to my 99 40 hp."
